9 Claims. (01. 24 -191) My invention relates to improvements in buckles, and has for its object to produce a buckle composed of parts combined in a simple and economical structure fully effective in operation and particularly adapted for the purpose for which it is designed.

Referring to the drawing in which similar numerals indicate identical parts- Figure 1 is a plan view of the completebuckle;

Figure 2 is a side elevation of Figure 1;

Figure 3 is a plan view of the buckle as applied toastrap; I

Figure 4 is a section on the line 4-4 of Figure 3; and, Y

Figure 5 illustrates, in perspective, the various parts of the buckle.

The buckle, asshown in the drawing, consists of a' frame member 1 having front and rear parallel bars 2 and 3 connected by side bars 4 and 5. The rear bar 3 extends outwardly beyond the side bars '4 and 5 to provide pintles 6. A tongue or clamping member 7 comprises a bar 8 having a series of teeth 9 on its front edge, and side bars 10 extending rearwardly, the rearward portion of each side bar being enlarged vertically above and belowthe planeof the bar 9 and centrally of each enlargement a is an aperture 11 inwhich the pintles 6 "of the frame member 1 are pivotally supported. A keeper having a bar 13 parallel with the bars 2 and 3 of the frame member 1 is also supported in the apertures 11 by pintles 14 formed on the lower ends of vertical parts 15 integral with the bar 13.

Figure 5 illustrates the parts of the buckle ready for assembly. The clamping member 7 is made of malleable metal and the enlargements of the side bars 10 are split at their rear ends and spread apart, as shown, to receive the pintles 6 of the frame member 1 and the pintles 14 of the keeper, and when the pintles Sand 14 are placed in the openings 11, the parts a of the enlargements are pressed together holding the frame and clamping members and the keepers securely in place but freely movable relative to each other.

In use, as shown in Figures 3 and 4, the keeper being in an upright position, a strap, as 16, is passed beneath the keeper and around the bar 3 of the frame member 1 and secured together, in 50 this instance, by rivets; the clamping member '7 is raised on its pivots and the running end of a strap 17 is inserted upwardly between the bar 2 of the frame member 1 and the bar 8 of the clamping member 7, and when the desired degree of tension has been obtained the strap 17 is bent over the bar 8 and under the keeper, the teeth-.9 of the clamping member 7 holding the strap 17 firmly between the bars 8 and 2, the teeth engaging with the fabric of the strap 17' and preventing slippage of thestrap.

The keeper is prevented from rocking toward the bar 8 by stops 18 on the side bars '10 of the clamping member. 7', so that the. strap 17 can be passed readily under the keeper without interference from thelatter which would .occur if the keeper was free to rock toward the bar -8.

The simplicity and ease of operation of my buckle are readily apparent particularly when utilized on harvester canvases for which it is mainly adapted, although it is equally valuable for use for other purposes.

Iclaim: i

1. Abuckle comprising a'frame memberinoluding a front bar and a rear "bar, side bars connecting said front and rear bars, the rear bar extending outwardly from the side bars, a clamping member including a front bar having a plurality of teeth on the front edge thereof adjacent the'front-frame bar, side bars on the clamping memberextendingto the rear bar of the frame member, and apertures in the rear ends of the side bars of the clamping member in which the rear bar of the frame member is pivotally journaled.

2. A buckle comprising a frame member including a front bar and a rear bar, side bars connecting the front and rear bars, the rear bar extending outwardly from the side bars, a clamping member including a front bar having a plurality of teeth on the front edge thereof adjacent the front frame bar, side bars on the clamping member extending to the rear bar of the frame member, apertures in the rear ends of the side bars of the clamping member in which the extensions of the rear bar of the frame member are pivotal- 1y journaled, and a keeper pivotally supported in said apertures.

3. A buckle comprising a frame member and a clamping member, each of said members comprising a front bar and a pair of side bars, one of said members having a strap receiving bar connecting the ends of the side bars, the other of said members being pivotally connected to the first member to swing about an axis coincident with said strap receiving bar, and a keeper piv- 1G5 otally secured on said clamping member, and means on the arms of said clamping member to limit the swinging movement of said keeper in one direction.

4. In a buckle which consists of a frame memno bucklebeing assembled by placing ,th pintles of the frame memberand keeper betvifeenj the arms of the bifurcations in the clamping member, respectively, then bending the ends of the bifurcations together to hold the frame member, the;

having aside bar at each end extending at right angles to the front bar thereof, a keeper member clamping member and the keeper in operative relation. l

5. In a buckle which consists of a frame member including a front bar and a r arp ro nece ed by side bars, the rear bar extending beyond the side bars to form pintles, a clamping member consisting of a front bar; and side' bars having their free ends bifurcated, and a keeper having I laterally extending pintles, the parts of said buckle being by placing theipintles of theframe member and keeper-between ,the arms'iof the i bifurcations in the clamping member, respectiveii-1 i 1y, then bending the,ends,of the bifurcations together to formanaperture in which the pintles of the clamping-member and the keeper are journaled. 1 a i '6. A buckle comprising a frame member including a'front'banand a: rear bar, sidebars connecting the front and-rear bars, a clamping mem-. ber including a front bar having a plurality of teeth on the :front edge thereof adjacent the front frame bar,- siderbars on theclamping member extending to the-rearrbar of the frame member, apertures inthe' rearends of thev side bars of the clamping member-inqwhich the rear bar arms of the bifurcations in the clamping manber, respectively, then bending the ends of the bifurcations together to form bearings in which the clamping member and the keeper ar journaled.

8. A buckle comprising a frame member including a front bar and a side bar at each end extending at right angles to the front bar, a clamping member including a front bar having a plurality of teeth on the front edge thereof adjacent the front bar of the frame member, and

comprising a keeper bar and an arm at each end extending at right angles thereof, one of said members having a' strap receiving bar connecting the arms thereof for receiving one end of a strap, and means on the ends of the arms of another of said members having bearing apertures in which the ends of said strap receiving bar and the ends of the arms of the third member are separately pivoted.

9. A buckle comprising a frame member ineluding a front bar and a side bar at each end extending at right angles to the front bar, a clamping member including a front bar having a plurality of teeth on the front edge thereof adjacent the front bar of the frame member, and having a side bar at each end extending at right angles-to the front bar thereof, a keeper membercomprising a keeper bar and an arm at :each end extending at right angles thereof, one of said members having a strap receiving bar'connecting the arms thereof for receiving one end of a strap, the ends of the arms of another of 1',
